Patent JP-S61186745-A (JP)
Title: Clean room
Inventor: NISHIKI KAZUHIRO
IPC: F24F7/06
Filed: 1985-02-13
Abstract: PURPOSE:To facilitate changing the layout and reduce the facility cost and running cost by disposing multiple blocks having a notch on floor slab, and providing a grating that forms an air duct between the floor slab and blocks. CONSTITUTION:The floor 21 comprises a floor slab 22, multiple rectangular box-like blocks 23 which have an annular notch in the upper rim and are relocatable, and a grating 24, and an air duct is made up by the floor slab 22, blocks 23 and grating 24. Therefore, when the layout of one of the semiconductor manufacturing systems 5 is changed to a large size semiconductor manufacturing system, it can be completed in a short period of time by simply changing the arrangement of the blocks 23. Further, the construction of the floor 21 does not employ any special method, but employs the prefabricated blocks 23 etc., and so, the construction work is simplified and completed earlier. Since HEPA filters 30... are disposed away from a position directly above the air duct 27 in the wafer work area 4, the air volume to be air conditioned can be made small, resulting in the downsizing of the air conditioning system and the reduction of running cost.

Title: Automatic exposure controller of ttl direct measurement camera
Inventor: YAMAZAKI MASABUMI
IPC: G03B7/099
Filed: 1981-02-23
Abstract: PURPOSE:To compensate the error of a film reflectance for TTL direct measurement, by carrying out the idle shooting for measurement of the film relfectance at a time point when the film frame number shows <=1 and storing the reflectance. CONSTITUTION:When a film load end switch 49 is closed, a lamp 51 glows up to make a gate circuit 44 conductive. The reflected light of the lamp 51 and given  from the shutter blade surface is measured a measuring element 4, and the  measured value is held at a storage capacitor 16. A difference between the measured value obtained the shutter is fully opened and the stored value is obtained  through a subtractor circuit 24 to be held at a capacitor 27. This difference value receives an A/D conversion to be stored in a memory circuit 45 via the  gate 44. This stored value becomes inherent to the difference of reflectances between the surface of the shutter blade and the film surface. The switch 49  opens when the film is advanced next to make the circuit 44 inconductive. Then  the lamp 51 is also turned off.

Title: Printed circuit board and production thereof
Inventor: KATAOKA TATSUO
IPC: H05K1/14
Filed: 1994-01-31
Abstract: PURPOSE:To obtain a printed circuit board having a low contact resistance and good environmental reliability by limiting a surface roughness (Rz) of a conductor circuit at a part to be bonded to, at least, an anisotropic conductive film within a specific range. CONSTITUTION:Three kinds of Cu foil are prepared: one has a roughness increased by depositing Cu grains on a glossy face at a connecting side which is a pattern side, and the two others have less roughnesses for comparison. The roughness (Rz) at the outer lead surface side of the Cu grain deposited Cu is 3.5 micrometers, that of the Cu as a comparison sample 1 is 1.3 micrometers and that of the other Cu as a comparison one 2 is 0.5 micrometers. The roughness of the pattern surface of a Cu foil on a Cu-lined laminated based to be connected is 1.3 micrometers. It is found that the contact resistance of the first one is the lowest. The contact resistance of the comparison one 2 having the lowest surface roughness is the worst. Hence Rz is preferably 1.5-5.5 micrometers.

Title: Vibration detection unit
Inventor: OOTAKE SADAO
IPC: G01V1/18
Filed: 1979-03-05
Abstract: PURPOSE: To simplify the structure of a vibration detection unit by detecting the vibration state dependently upon light receiving change of a photo detecting material.  
     CONSTITUTION: Light emitting element 9 and photodetector 10 are inserted from the lower part and are fixed to a pair of inclined holes 5 and 6 which pass through pedestal 2 toward the center of fixed hole 3. When ball 4 exists in the home position, the light radiated from light emitting element 9 is reflected on the lower part of ball 4 and is received by photo detector 10, and photo detector 10 indicates, for example, the low resistance value as a signal of non-vibration. When vibration occurs to remove ball 4 from the home position, the light radiated from light emitting element 9 cannot be reflected and is not received by photodetector 10. Under this state, photodetector 10 indicates the high resistance value as a signal of vibration- state. Then, after vibration stops, ball 4 is put on the home position by magnet 13, etc.

Filed: 1982-02-22
Abstract: PURPOSE:To judge at a look, whether an operation switch is switched to either mechanism control circuit or not by associating display with the switching the operation switch to the 1st or the 2nd mechanism control circuit. CONSTITUTION:The operation signal of the operation switch 30 is inputted to AND circuits connected to the 1st and the 2nd mechanism control circuits 12 and 22, but the other-side input terminals of the AND circuits are connected to output terminals Q and Q' of a J-K flip-flop 42 and invariably inverted outputs appear at the terminals Q and Q', so only one of two AND circuits operates in response to the operation signal of the operation switch 30. Namely, when the operation switch 30 is operated, only one side between the 1st and the 2nd mech anisms 11 nad 21 operates. Its operation state is displayed on display circuits 16 and 26 connected to the outputs Q and Q' of the J-K flip-flop 42.

Title: Laser-induced thin film deposition apparatus
Inventor: ITO HIROMI
IPC: H01L21/31
Filed: 1986-02-07
Abstract: PURPOSE:To effectively use the ion element for thin film deposition and improve the deposition rate by causing the electric field application direction to match the direction in which the ion runs to the substrate. CONSTITUTION:In the laser CVD method without DC electric field, the ions generated in the laser beam diffuse also into the space in the opposite side of the substrate and such ions do not contribute to deposition of film. However, when the DC field is applied and such direction is matched with the direction is which the ions which contribute to deposition of film run to the substrate 2, the ion element among the free radical generated by optical reaction and ions is effectively used for deposition of thin film, realizing improvement of deposition rate. Moreover, impact on the substrate surface by the accelerated ions further improves close contactness between the substrate 2 and thin film and density of thin film, thus solving a problem in the optically excited CVD method that density of deposited film is low.

IPC: B21B1/46
Filed: 1986-02-12
Abstract: PURPOSE:To prevent the generation of a thickness deviation or local ruggedness by subjecting a sheet bar to a specific amt. of surface light draft reduction prior to finish rolling. CONSTITUTION:A surface light draft reduction mill 3 is provided in order to preliminarily condition the surface characteristic prior to the finish rolling and the sheet bar 5 is subjected to <=10% surface light draft reduction. The metal flow is thereby induced in the transverse direction of the sheet bar 5 in the extreme surface layer thereof by which the thickness deviation in the transverse direction is advantageously corrected without affecting the camber generated in the longitudinal direction. The metal flow is easily generated in either of the longitudinal and transverse directions by such light draft reduction and therefore, the surface characteristic of the sheet bar 5 concerning the local ruggedness is advantageously corrected as well.

Title: Method and device for continuous casting
Inventor: FUKASE HISAHIKO
IPC: B22D11/06
Filed: 1984-02-15
Abstract: PURPOSE:To increase the contact area between solidified shells and a moving casting mold and to improve cooling efficiency and production efficiency by obviating abrupt generation of the solidified shells when a molten metal contacts the moving mold thereby preventing waving of the solidified shells owing to thermal strain. CONSTITUTION:Rolls 1', 1' are rotated in an arrow direction and solidified shells 2 are formed along the surfaces of the rolls 1', 1' and are cast as a hoop 5. The surfaces of the rolls 1', 1' are not cooled right after contact with a molten metal 4 and are heated by the shells 2 within a gamma deg.-0 deg. range so that the rolls are brought into contact with the molten metal 4 at a relatively high temp. decreasing gradually. If the shells 2 are gradually formed, the generation of waving in the shells 2 owing to thermal strain is prevented and the shells 2 are formed flatly along the surfaces of the rolls 1', 1'. The contact area between the shells 2 and the surfaces of the rolls 1', 1' are thereby increased. If the rolls are thereafter cooled within the range from beta to gamma, the extreme decrease in the heat extraction rate of the rolls 1', 1' is obviated, by which the cooling efficiency is improved [see curve (b)] and the productivity is improved.
